Boston Mineral Club
Welcome to the Boston Mineral Club website! If you have suggestions, questions or comments about the site, please use the Contact page.
You do not need a college degree in earth sciences to join the club! We are open to all. We welcome and encourage new members to join the club. Membership
The Boston Mineral Club (BMC) was founded in 1936 to "promote the study and collecting of rocks and minerals, to encourage friendly cooperation among mineralogists and collectors, [and] to promote the study of mineralogy and related arts and sciences coming within the purview of earth sciences..."
In the pursuit of these goals, the BMC offers educational programs at club meetings, mineral collecting field trips, a newsletter, and access to our mineralogical reference library.
The Boston Mineral Club is a member of the American Federation of Mineral Societies and the Eastern Federation of Mineral and Lapidary Societies.
The Boston Mineral Club is proud of its long tradition of conducting field trips to collecting localities throughout the New England area. Information about trips planned for the current year is published in our newsletters which can be found in the members only area of the website.
The club also organizes occasional trips to localities outside of New England. Previous destinations have included Nova Scotia, Kentucky, Georgia and Arizona. You can view photos of our 2009 trip to Nova Scotia here: recent trip to Nova Scotia.
Information about the regular monthly meetings of the club can be found on the meetings page.
The October meeting of the Boston Mineral Club will feature a presentation by Tony Mariano and his son, Tony Mariano Jr. on the use of cathodoluminescence by the exploration geologist. This talk will not only help to educate us about this mineral identification technique but will also treat our eyes to some colorful and fascinating images.
Here is the abstract that they have provided for their presentation:
The utilization of cathodoluminescence (CL) in mineral exploration has been in existence for almost fifty years. The most valuable aspect of using CL in geology and materials science is in the enhancement of the visibility of diverse microscopic phases and features that might otherwise be totally missed by standard petrographic observations. For the exploration geologist, CL instrumentation is a relatively inexpensive tool that can give information that is otherwise obtained by the use of more elaborate instruments and chemical analyses. This is especially of value to exploration geologists when access to universities or research facilities is not available.
If you are interested in learning more about this subject prior to the presentation some basic information about the methods can be found at the following web addresses:
The third URL is a reference to a collection of abstracts from a 2011 conference on cathodoluminescence. It contains abstracts for numerous papers and provides an interesting sampling of the uses of cathodoluminescence in various fields including geology.
To complement this presentation about a method employing microscopic imaging techniques, all members are encouraged to bring in one or two specimens they would like to examine under a microscope. We will try to have several standard optical microscopes available for use and will also try to capture images of some specimens (as time allows). This is your chance to see some of those tiny crystals hiding in the small cavities of rocks you have collected!
The Harvard Mineral Museum will be open to us prior to the meeting starting at 7 PM. Those wanting to use a microscope to view specimens should come around 7:15 PM. Everyone should plan to arrive by 7:30 PM to socialize . We will start the meeting presentations around 8:00 PM, and after the presentation is completed the meeting will conclude with our traditional mineral specimen raffle.
Visitors are always welcome to attend BMC meetings, and this meeting provides a good opportunity for you to invite a friend so that they can see what the club is all about. I hope to see you there!
